Recently I found my DVR's display frozen with animated pixels and lines going through the menus. I unplugged it (there is no off switch) and plugged it back in, and the loading screen also became fuzzy and pixelated also. Ultimately my DVR will not load at all. The hard drive light is solid red. I opened the unit and there is no visible burns or damaged components on the PCB and all connections are secure. Any insight would be great!
